For instance, you might want to publish a resource action to install software on a provisioned machine.
Instead of providing the consumer with a static list of all software available for download, you can
dynamically populate that list with software that is relevant for the machine's operating system, software
that the user has not previously installed on the machine, or software that is out of date on the machine
and requires an update.
To provide custom dynamic content for your consumer, you create a vRealize Orchestrator script action
that retrieves the information you want to display to your consumers. You assign your script action to a
field in the form designer as an external value definition. When the resource or service blueprint form is
presented to your consumers, the script action retrieves your custom information and displays it to your
consumer.
You can use external value definitions to supply default or read-only values, to build boolean expressions,
to define constraints, or to provide options for consumers to select from lists, check boxes, and so on.
Working With the Form Designer
When you create XaaS blueprints, custom resource actions, and custom resources, you can edit the
forms of the blueprints, actions, and resources by using the form designer. You can edit the
representation and define what the consumers of the item or action see when they request the catalog
item or run the post-provisioning operation.
By default, any XaaS blueprint, resource action, or custom resource form is generated based on the
workflow presentation in vRealize Orchestrator.
